FIELD OF THE INVENTION

The present invention relates to security locks for laptop and/ornotebook computers and other hand-held electronic devices, such as cellphones, personal digital assistants, personal music and/or video players(i.e. iPod®) and the like.

BACKGROUND OF THE INVENTION

Notebook computer or other personal electronic devices are increasinglyused by students at educational institutions. They are also used byworkers at job sites. Notebook computers are often referred to as laptopcomputers, meaning a portable, foldable computer which can be used whilepositioned upon the user's lap. In some instances, “laptop computer”refers to the term used in the trade for an older version of a largerportable computer. However, with increasing streamlining and downsizingof portable computers, compact, smaller versions are referred to as“notebook computers”, but the terms are generally interchangeable.

In order to safeguard the personal electronic device, such as a notebookcomputer, it must be shut down, closed and transported by the user.

However, it is often advantageous for the user of a notebook computer totake a break and leave the computer open and operable at a work stationor library study carrel, with other papers and books left at theircurrent open position. This leaves the personal electronic device, suchas a notebook computer vulnerable to theft.

Moreover, in the commercial retail environment, it is advantageous todisplay consumer electronic devices, such as notebook computers, cellphones or personal digital assistants in a secure but visuallyaccessible display.

OBJECTS OF THE INVENTION

It is therefore an object of the present invention to provide a securitylock for a personal electronic device, such as a notebook computer in anopen position.

It is also an object of the present invention to provide a commercialretail display which allows visual access to notebook computers, cellphones and personal digital assistants while safeguarding these devicesfrom shoplifting theft.

Other objects which become apparent from the following description ofthe present invention.

SUMMARY OF THE INVENTION

In keeping with these objects and others which may become apparent, thepresent invention is a desk surface locking base which holds a notebookand/or laptop computer, or a personal electronic device such as cellphones, personal digital assistants, personal music and/or video players(i.e. iPod® of Apple Corporation) in a secure but open position. Whenlocked in place, the notebook computer or other personal electronicdevice is secure from being taken away from the surface to which it islocked. Furthermore, taking advantage of software and/orsoftware/biometric security systems, the computer or other personalelectronic device will also be unusable by unauthorized individuals whenits owner is away from the area for a break, telephone call, or othershort-term pursuits. With a few keystrokes, the owner of the computer orother personal electronic device can resume activity in exactly the sameplace as when activity had been suspended. This is especially useful forleaving an active computer or other personal electronic device on astudy desk or library carrel.

In one embodiment, the notebook computer or other personal electronicdevice lock includes a locking base having a receptacle for receiving adistal end of a pivotable locking member pivotably attached at aproximal end thereof to the locking base. The locking member locks thecomputer screen between it and the locking base. The locking base isfastenable to a notebook computer work surface, such as a desk top orother table surface, in the vicinity of the notebook computer. A pinlock secures the locking bar across the display screen portion of thenotebook computer or other personal electronic device and into a hole inthe locking base, thereby securing the notebook computer or otherpersonal electronic device in a locked position within the components ofthe notebook computer or other personal electronic device lock.

In another embodiment, the locking base is screwed or otherwise fastenedto the work surface in a permanent fashion. A locking collar is thenremoved from the base and then placed over the liquid crystal display(LCD) screen of the open notebook computer or other personal electronicdevice within the framework of the locking base. A lock, such as apadlock, is then used to lock together the locking collar and thelocking base, thereby making it impossible to remove the notebookcomputer or other personal electronic device from the work surface.

In this embodiment, the notebook computer or other personal electronicdevice locking assembly includes a locking base for being secured to aworking surface, wherein the locking base has a rear wall to receive akeyboard portion of the notebook computer or other personal electronicdevice with a screen portion of the notebook computer or other personalelectronic device in the open position resting parallel to the rearwall. The rear wall has a rearwardly extending locking flange along atop edge of the rear wall. A locking frame includes a second rear wallhaving side walls and a locking bar joining the side walls, wherein thelocking frame is adapted to slide over the screen portion of thenotebook computer or other personal electronic device in the openposition, with the second rear wall between the screen portion and thefirst rear wall and the locking bar extends across a front surface ofthe screen portion.

This second rear wall has a rearwardly extending locking flange along atop edge of the second rear wall on top of, and flush against, thelocking flange of the first rear wall. The side walls of the lockingbase have tabs bent toward the computer or other personal electronicdevice, with the locking bar falling behind the bent tabs, when thelocking frame is deployed on the notebook computer or other personalelectronic device, thereby preventing removal of the notebook computeror other personal electronic device from the locking base. Additionally,locking holes in both flanges are aligned with each other to receive apadlock to lock the locking frame to the locking base.

Fasteners are employed to attach the locking base to the workingsurface, so that the fasteners are kept under the keyboard portion ofthe computer or other personal electronic device.

The lower edges of the rear walls are raised a sufficient distance toallow access to connectors on a rear surface of the keyboard portion ofthe computer or other personal electronic device.

Preferably, an optional cage is attached to a rear of the first rearwall to house an auxiliary battery, charger or battery eliminator.

In an alternate embodiment, an elongated framework of the locking baseis used that supports the LCD screen of the notebook computer at theproper viewing angle, just as in the preferred embodiment. In this case,however, the locking device is a transparent screen cover, such as ofLEXAN® polycarbonate, which is placed over the screen and then locked tothe locking base with a lock, such as a padlock. This panel is also ascreen protector. This is a desirable feature for a demo station at aretail outlet, to display and demonstrate a notebook computer oradvertise another product. Using an auxiliary locking flange, thisembodiment is also compatible with the locking collar of the preferredembodiment. This use mode does not obscure viewing of the LCD screendirectly, when viewing the display screen through the transparentpolycarbonate sheet. Similar smaller locking bases with polycarbonate orother strong locking panels can be used to display and demonstrateconsumer devices, such as personal digital assistants (PDA's),scientific calculators, and cell phones, on store shelves.

This embodiment may also have an optional accessory cage made of heavywire mesh or perforated metal, which can be attached to the back portionof the locking base. This securely contains a battery charger/eliminatorfor the notebook computer.

In this embodiment with a transparent screen cover, the notebookcomputer or other personal electronic device locking assembly includes alocking base secured to a working surface, with the locking base havinga pair of side walls and a rear wall to receive a keyboard portion ofthe notebook computer or other personal electronic device, wherein ascreen portion of the notebook computer or other personal electronicdevice is oriented in the open position, resting adjacent to the rearwall. This rear wall has a rearwardly extending locking flange along atop edge thereof.

The transparent locking frame has a surface adapted to rest adjacent to,or against, a front surface of the screen. A top wall is adapted to restagainst a top surface of the screen portion of the computer or otherpersonal electronic device, with a rear wall extending down from the topwall, adjacent to a rear surface of the screen portion of the notebookcomputer or other personal electronic device. A rearwardly extendsflange from a bottom edge of the rear wall, with the rearwardlyextending flange positioned adjacent to the rearwardly extending lockingflange of the locking base.

In this embodiment, locking holes in both flanges are aligned with eachother to receive a padlock, to lock the transparent locking frame to thelocking base.

In this embodiment, an optional shelf or shelves may be provided todisplay handheld electronic accessories, such as cell phones, PDA's,calculators, video game controls, etc., for retail viewing purposesthrough the transparent screen cover.

In yet another embodiment, the pivoting locking rod, locking collar ortransparent polycarbonate locking panel is replaced by a telescopingrod, a vinyl covered steel cable, or a flexible tubing covered chain.Like the pivoting rod version, this embodiment therefore eliminates theremovable portion of the locking base system (such as the locking collaror transparent polycarbonate panel), and instead uses a locking devicethat is permanently attached to one side of the locking base itself.This locking device is also locked with a padlock by first passing thedistal end of the locking member through a hole in the opposite sidepanel member of the locking base thereby preventing removal of thenotebook computer or other personal electronic device.

In this embodiment, the notebook computer or other personal electronicdevice locking assembly includes a locking base secured to a workingsurface, with the locking base having a pair of side walls and a rearwall to receive a keyboard portion of the notebook computer or otherpersonal electronic device. A screen portion of the notebook computer orother personal electronic device is held in the open position, restingagainst and/or parallel to the rear wall, with the side walls extendingpast a front surface of the screen portion. A telescoping locking bar orflexible locking cable is hinged at one end to one of the side walls, infront of the screen portion. An opposite end of this telescopic orflexible locking bar or cable has a plug with an opening therethrough.An opening in the other of the side walls is configured to align withthe opening in the plug, when the locking bar is rotated across a frontsurface of the screen portion, with the plug positioned adjacent theother of the side walls to accommodate a padlock, to lock the notebookcomputer or other personal electronic device into the locking base.

In a further embodiment the computer lock or electronic device lock isattached to a horizontal desk or work surface via a locking base whichis separate from the computer lock itself. The computer lock is thenslipped into the locking base from the side and both the computer andlocking base are then secured to the work surface. In this manner, noholes are drilled into the work surface, and the locking base isremovable yet secure. The locking base is secured to the work surface bya clamp which goes over the front edge and engages the bottom surfacevia a screw with a pointed end which is tightened so as to indent theunderside and thereby attach. The screw itself can have a security headsuch as an allen socket with a concentric protruding rod which preventsthe use of a simple allen wrench. A specialty security allen wrench witha hole to accommodate the protruding rod is required for the initialattachment as well as subsequent removal. A side bracket attached to theclamp also accommodates a mailbox type key lock which can be used todeny access to the attachment screw head for an extra measure ofsecurity. If the key lock is used, an ordinary non-security screw can beused since the lock tang itself will adequately secure the screw. Thecomputer lock used with this embodiment has a horizontal frame memberwith two vertical side brackets at each end attached to base plateswhich can be screwed to a work surface as in the previous embodiments orused with the locking base.

A bar which is captively attached to one bracket secures the bottom ofthe notebook computer display when the other end is passed through ahole in the distal bracket and a key lock is then slipped over the barend which has a groove compatible with the lock.

In an alternate embodiment wherein a clamp wraps around a work surfaceto lock the notebook computer or other personal electronic device inplace, the clamp itself may be the locking base itself, connected to thepersonal electronic device by a cable or other locking connection.

In another embodiment, the above noted computer lock or electronicdevice lock is attached to directly to a horizontal desk or work surfaceby fasteners.

Yet another embodiment of a computer lock, the lock has a continuouslywidth adjustable feature to accommodate computers with a variety ofdisplay width sizes. It includes a left portion with vertical bracket,base attachment plate, horizontal member, and captive lock bar. A rightportion has a vertical bracket, base plate and hollow horizontal membersized to receive the left horizontal member in a telescoping fashion.The locking bar is fabricated of a left portion which is a threadedtubing member having coarse threads. The right portion of the lockingbar is a solid member with mating external threads on its long end. Thiscomputer lock is used with the locking base of the previous embodimentto take advantage of its telescoping feature. (It can also be screweddown to a work surface directly, but the adjustable feature would bedefeated unless screws are moved to other adjustment holes.)

To use the computer lock, the user places a notebook computer within theside brackets, and then pushes the sides in adjacent to the computerdisplay. Then the user screws the distal end of the locking bar in orout to facilitate the end fitting through the lock holes on the rightbracket. When locked with a key lock, the bar will secure the computerand prevent the spreading of the side brackets.

In a related embodiment, the width adjustable feature is discreteinstead of continuous. Although any suitable width adjustment mechanismcan be used, a suggested type uses a peg which fits into a hole in thelarger of the two telescoping members. The inner telescoping member hasa series of holes which define the width steps when in registration withthe single hole of the larger/outer telescoping member. The peg locksthe outer hole to one of the inner holes.

In another embodiment, the locking base described above is integratedwith a computer lock or electronic device lock in a single unit. Thusthe computer or other personal electronic device lock is now directlyattached to the work surface via a clamp that goes over an edge of awork table and locks into the bottom surface of the work table.

In yet a related embodiment, the integrated locking base/computer orother personal electronic device lock has two pivots from the clamp endto the computer or other personal electronic device lock so that muchpositional freedom is afforded the locked computer or other personalelectronic device over the work surface. For example, this pivotingembodiment can be used on corners of work tables.

In a preferred embodiment for consumer use, a low profile locking basewith a narrow footprint is used. Due to its smaller dimensions, lessmaterial is required. Since it can be stamped and formed from a singlerectangular sheet with little waste, the process for manufacture is veryefficient. Heavy gage aluminum sheet or stainless steel sheet can beused. It is therefore lighter and more economical.

In one application this locking base is permanently screwed down to thework surface, and the user would have his or her own pin lock, to securethe locking bar across the display portion and into the base back,thereby securing the notebook computer or other personal electronicdevice.

However, the preferred mode of use for this embodiment is to combine thelocking base with a cable and clamp as a portable kit which fits into aconvenient tubular carrying case. The clamp is attached to the worksurface or to a table leg or any convenient non-movable structure in thevicinity.

This clamping of the clamp to a work surface is accomplished bytightening a clamp screw against the work surface, such as a table topor desk top. The clamp screw extends from a clearance hole in acontainer, such as a short tube, with a large axial hole at the distalend that accommodates the screw head. An appropriate tool compatiblewith the type of screw head used is entered from the distal hole totighten or loosen the clamp while also capturing the short tube; thiscan be an allen wrench, a screwdriver, or a hex head driver asappropriate.

The cable has a small end ferrule with a transverse hole on one end anda ferrule with a larger end attached to the distal end of the cable. Atransverse hole in the lower portion of the short tube accepts theferrule and cable, but is sized to prevent access to the larger end ofthe distal ferrule.

In use, the clamp is attached to the structure, such as a desk top, asdescribed; then the cable is threaded through the transverse hole in theshort tube. The end of locking bar is passed through the cable ferrulewith the transverse hole prior to locking it to the locking base. Inthis manner, although the computer or other personal electronic devicecan be moved around on the work surface, it is secured by the cable.

It is noted that the cable being threaded through the transverse hole inthe container, such as the short tube, denies access to the clamp screwhead. The cable must be removed before the clamp can be loosened fromunderneath of the desk top or other work surface.

In an alternate embodiment of the clamp screw subassembly of thispreferred embodiment, no tool is required to tighten or loosen theclamp. For example, a hollow knob with a captive locking member, such asa clamp screw, emerging from a clearance hole in an end cap, is used.

The clamp screw has a tall head and can be a hex, square or othergeometric configuration. A recess with a configuration matching thescrew head is formed into the inside surface of the end cap such that aslight pull on the knob against the captive screw head (i.e.—away fromthe clamp) will seat the head into the recess with a slight turn. Thusthe end cap is a socket wrench used to either tighten or loosen theclamp.

A strategically placed offset transverse hole is prevented fromaccepting the cable by the screw head if the screw head is seated in thewrench recess.

By pushing up on the end of the knob (toward the clamp), clearance forthe cable to enter through the transverse hole adjacent to the screw andbetween the head and end cap is formed. Thus, the screw head is spacedapart from the end cap socket wrench recess as long as the cable ispresent. If the knob is turned while the cable is installed, it willjust turn freely with no ability to loosen the clamp even if force awayfrom the clamp is used. The cable must be removed before the clamp canbe loosened.

In a further embodiment of this invention, a notebook computer or otherpersonal electronic device is provided with a security hole through thehinge area between the display and the base, through the edge of thedisplay, or diagonally through a corner of the base. A protruding spikeor rod, with a head on one end and a transverse hole near the distalend, is used to secure the computer or other personal electronic device.The spike or rod is inserted through the security hole, and a ferrule onthe end of a secure cable is then inserted through the transverse holeof the spike or rod, and is locked by a pin lock compatible with thegroove feature at its distal end.

In a variation of this embodiment, the spike or rod is replaced by acaptive security rod with a transverse hole. In one design, thissecurity rod is stored in a one end of the hinge in a directionco-linear with the hinge.

In an alternate design, the security rod can rise vertically from thecomputer base or base of the personal electronic device. A small knob isattached to grasp the rod which may be stored in the recess by aquarter-turn feature or by a magnetic force.

An alternate type of spike locking feature does not depend on the use ofa secure cable; a longer separate spike is used. It is designed topenetrate through a hole in a convenient location in the computer baseor personal electronic device base from the top, through the basethickness, and further through a pre-drilled hole in the table or desktop. This long spike has a transverse hole which emerges beneath thetable top. A pin with a groove near its distal end is then insertedthrough the transverse hole of the long spike and locked by a pin lock.

In a further alternate embodiment, the protruding rod may take the formof a thin rigid or flexible strip. The strip may be inserted within athin, longitudinally extending hole, such as a slot, within the body ofthe personal electronic device, such as a notebook computer.

On the other hand, if the notebook computer has a hinge between thedisplay screen and the main body of the personal electronic device, suchas in a hinged notebook computer, cellphone or personal digitalassistant (PDA), then, if the strip is flexible, it can be insertedwithin the hinge gap between the display screen and main body of thedevice, such as a keyboard portion of a notebook computer.

The thin, flexible or rigid long rectangular strip includes a wedge stopat a proximal end and a distal end being thin enough to weave within theslot of a personal electronic device, or through the hinge gap of ahinged instrument such as the gap between display and keyboard of anotebook computer. If the rectangular strip is flexible, preferably, thethickness of this strip is between 0.004 inches and 0.064 inches. Thecomposition of the flexible strip is flexible reinforced plastic ormetal such as heat treated steel shim stock. Springy stainless steelshim type stock is also a useful material as well a variety of othersteel alloys.

After the distal end of the locking strip is passed through the slot inthe personal electronic device, or alternatively through the hinge gapin the device being secured, it is clamped by a strip-holding lockingclamp, which itself is attached to the work surface, or is otherwisesecured to it as by a secure cable. The strip-holding clamp may havelocking jaws with serrations which aggressively grip the distal end ofthe locking strip when a key lock is closed by a matching key. The lockis similar to a mailbox lock with a tang that engages a lock recess inthe lower base section of the locking clamp thereby overcoming a springforce which keeps the jaws apart slightly when not locked. The key isalso used to unlock the two mating jaws to release the locking strip andthereby unsecure the device. In a library environment, both the key fora particular clamp as well as a locking strip can be borrowed from alibrarian to secure the device in a locked state.

In an alternate embodiment of the locking clamp, the distal end of thelocking strip is inserted in the clamp end through a slot formed by twoupright members and a robust leaf spring attached to a pivoted handle.The handle is pressed down toward its distal end (thereby offering muchmechanical advantage for the operation) bending the leaf spring therebyclamping the distal end of the locking strip in a slight recess withtransverse serrations in the clamp base. The shackle of an ordinary keyor combination padlock is then passed through loops attached to theclamp base as well as a loop at the distal end of the handle (inregistration) and locked. By locking the handle in a down position, thedevice is kept secure by frictional forces opposing pull-out arisingfrom the normal spring force. In this manner, any person with anappropriate padlock and a locking strip can lock his own device to awork surface using any available clamp. The need to receive from andreturn to a librarian a specific key is eliminated.

In an alternate embodiment of the locking strip itself, whether it beflexible or rigid, a large hole is provided near the distal (free) endof the strip. This permits a variety of methods of locking the strip tothe work surface in lieu of a clamp. In one method, a round stud with atransverse hole near its distal end is attached to the work surface in aperpendicular orientation (sticking up). The locking strip is insertedthrough the hinge gap in the device to be locked and then the hole inthe locking strip is passed over the stud; the shackle of an ordinarykey or combination padlock is then passed through the transverse hole inthe stud thereby locking the strip to the work surface. In a secondmethod, a secure cable with a stud at its end is provided. The cablestud is passed through the hole in the locking strip, and then a cablelock that fits the stud is locked onto it thereby locking the strip tothe secure cable. In a third method, a free cable with a stop memberpermanently attached at one end is passed through the hole in thelocking strip. The cable is then looped or otherwise secured to (oradjacent to) the work surface.

In another embodiment of this invention, a locking device specificallyfor an iPod® or similar music and/or video playback devices isintroduced. While iPod®'s are small slim devices designed for carryingin a shirt pocket, there are some situations for which a locking deviceis prescribed. The lack of security in a typical dormitory room can becounteracted by locking an iPod® to a desk top at night or when away.Other areas such as school labs might be another venue where such adevice might be used. This embodiment consists of a sturdy metal framewhich encircles the iPod®, a clamp which can be attached to a desk ortable top, and a rod which secures the frame to the clamp with the aidof a pin lock. The clamp has a groove in the upright section of itsframe which receives a tab from the bottom end of the iPod® frame. Withthe tab in the clamp groove and the rod inserted through holes inextensions on the sides of the iPod® frame and also through an offsethole in the clamp locking knob, the iPod® is secured and the clamp knobcannot be turned to loosen the clamp.

In the preferred embodiment of the iPod® locking device, a frame withfive sides is used to house and secure the iPod® with open areas asrequired to not impede its use. The iPod® is slid into the open edgeslot and secured by bridging the two holes in registration with eachother which extend from the top and bottom surfaces of the open edge. Aferrule at the distal end of a secure cable is engaged by the samepadlock hasp which engages the two holes. Alternatively, the padlock canengage the holes thereby securing the iPod® within and also engage ametal ring attached to a backpack, or it can engage a belt loop or otherattachment to clothing, luggage, or purse; for these methods, no cableor cable clamp is required.

A further alternative embodiment of the iPod® security device includes aframe with two right angle portions hinged together such that they canbe closed with the distal ends meeting thereby forming a rectangularframe. The frame members have bent-over tabs which would capture aniPod® securely when closed. The closed position also puts two loops inregistration at the distal ends, one on each swinging portion. Theseloops can be used to lock the two swinging portions together capturingthe iPod® and connecting it to either a secure cable or to a backpack orarticle of clothing as in the preferred embodiment.

Four further alternative embodiments of locking devices for music and/orvideo playback devices, such as the various models of iPod®, are alsoincluded in this invention. Although all three can be used with a securecable as in the previous embodiments, they are optimized for attachmentto belt loops since they orient the playback device with the screenupside down while dangling to facilitate easy reading when lifted ninetydegrees while still attached.

The first of these embodiments includes a frame with an open side alongthe long edge to permit the playback device to be inserted. The playbackdevice is secured within the frame by engaging the hasp of a padlockwithin a hole on a side extension of the top edge of the frame; the haspbecomes an interference preventing the withdrawal of the music/videodevice from the frame.

The next alternative embodiment has a band loop near the top of theframe sized to permit the music/video playback device to be insertedthrough it to the distal hook in the frame which engages the front ofthe device near the center of the screen's top edge. Thus the insertionopening is as wide as the shorter dimension of the playback device. Thetop band loop has a short central extension on the front side with ahole to accept the hasp of a padlock. The hasp then becomes aninterference preventing the withdrawal of the device from the framethereby securing it to a belt loop or ring which is also engaged withthe padlock hasp.

The third of the four alternative embodiments is extremely compact. Itis sized to capture the music/video playback device at two diagonalcorners. This locking device is a flat bar which is positioned incontact with the back side going diagonally from top to bottom. Thedistal end of the bar has a four-sided small rectangular recess orpocket which engages the playback device at a corner of the screen witha small portion over the screen frame. The proximal end of the diagonalbar has a small three-sided rectangular recess or pocket which permitsthe opposite bottom corner of the playback device to nestle within therecess with the bar against the back side. The sides of this proximalrecess are higher than the thickness of the playback device and have twoorthogonal holes placed just above the device thickness. The music/videoplayback device is secured within the diagonal bar when the hasp of apadlock is passed through the two orthogonal holes thereby creating aninterference preventing the bottom corner of the music/video device frombeing lifted up away from the diagonal bar.

In a fourth embodiment, a sleeve frame is provided for slidably securinga personal electronic entertainment device within, wherein a frame plateforms a base from which short walls extend in perpendicular arrangement,and a hasp tab is provided for engaging a hasp to prevent removal of themusic player from the frame.

A security cable for attachment to laptop or notebook computers has beenon the market for some time. It is a plastic clad steel cable with aloop formed at one end and a special lock at the other end. The lock(whether key type or combination) has a locking feature at its distalend which is designed to fit into a mating recess in the computer; whenlocked in place, the cable is attached to the computer device. The cableis designed to be secured to a handrail, pipe, or any other convenientanchoring feature; the lock end is passed through the loop end engagingthe anchoring feature prior to locking into the computer recess.Unfortunately, many work areas do not have such secure attachments inthe vicinity. Such a cable is usually then just looped around a table orchair leg thereby compromising security, unless it is permanentlysecured for single location use.

In a further embodiment of this invention, a cable clamp that canaccommodate the prior art security cables with a formed loop at one endconverts the cable to secure portable use even in the absence of asecure anchoring attachment in the vicinity. This cable clamp is similarto the cable clamp described earlier which uses a transverse hole in anoperating knob, which prevents loosening once a cable is installedthrough the transverse hole. A modification to accommodate the insertionof the looped end of the security cable part way, through a transverseslot in the operating knob, permits this desktop or tabletop securecable clamp to be used with such a cable having a permanently attachedlock at the other end.

A further embodiment of the secure cable clamp permits adjustment of thegrip range of the clamp beyond that which is accommodated by thetightening screw. This is important for the use of portable devices inmany venues where the thickness of table or desktop cannot beanticipated. The clamp frame is redesigned as an upper part and aseparate lower part attached via a body screw which is rigidly attachedto the top part, but permitted to swivel in a threaded hole therebyadjusting the grip range by rotating the lower part relative to theupper part.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows locking base 1 for a notebook computer lock, which issecured to a working surface by fastener holes, such as screw throughholes 4 in base mounting pads 3. A back surface 10 is tilted at angle“X” to provide a good viewing angle of the computer screen. Side panelmembers 6 with bent tabs 7 provide a space for sliding locking collar 2.Locking flange 8 with a locking hole, such as padlock hole 9, is used tosecure locking collar 2 with flange 14 via hole 15, which is inpositional registration with hole 9 when mated. Width “W” is wider thanthe widest notebook computer or other personal electronic device to beaccommodated by this locking base system. Locking bar 12, attached tothe distal ends of sides 13, actually secures the notebook computer orother personal electronic device. This is the preferred embodiment. Thedisplay screen portion rests within space 16 between sides 13. In use,the keyboard portion of a notebook computer or other personal electronicdevice would deny access to the fasteners, such as retaining screws, inholes 4.

Side panel members 6 may have one or more ports 6 a to accommodatecomputer cables therethrough.

FIGS. 2, 2A, 2B and 2C show how locking collar 2 is placed over notebookcomputer screen 19 and then upon flange 14, and is locked to lowerflange 8 via a lock, such as padlock 20. Keyboard 18 fits between sides6. Space 5 is created by a raised back panel 10 so as to permit accessto a variety of connectors at the back of computer keyboard portion 18.FIG. 2 also shows an optional compartment 42 for a power sourceaccessory 43, such as an auxiliary battery charger or batteryeliminator, wherein compartment 42 extends between power flange 8 andfurther lower flange 8A.

FIG. 2D shows the notebook computer being used by a person at a workstation;

In an alternate embodiment shown in FIG. 3, upright portion 25 supportsthe entire height of screen 19 above raised back panel 10 mounted uponbase pads 3. This can also be shown in FIG. 4. FIG. 3B shows anotherexample of a lock 20 a, which can be used in lieu of padlock 20.

FIG. 3A shows a further alternate embodiment where shelves 36 and 36 aare depicted supporting electronic handheld devices such as folding cellphone 37 a, upright cell phone 37 b, marine VHF radio 37 c, personaldigital assistant 37 d, calculator 37 e and video game pad controller 37f.

A transparent panel, such as LEXAN® polycarbonate panel 30, shown inFIG. 5, is used as a locking frame, by sliding it over screen 19 withinthe four tabs shown in FIG. 3 at the distal corners of upright 25.

Panel 30, shown in FIGS. 4-7, has a top portion 32 and a locking flange33 with padlock hole 35. In use, this hole is in positional registrationwith that of upper locking flange 27 shown in FIG. 4. A padlock 20 orother small lock 20 a can be used to secure the two members together.Front face 31 of transparent panel 30 protects the surface of computerscreen 19. This can be used to advantage in a retail demo environment.Alternately, the locking collar of FIG. 1 can be used with base of FIG.3 by locking into lower locking tab 26; this would offer a betterunencumbered view of screen 19.

FIG. 8 shows the addition of an optional battery pack housing cage 42feature to the locking apparatus of the embodiment shown in FIG. 1,although it can be used with any of the embodiments herein;

The optional power source component 42 of FIGS. 2 and 8 can be added toany of the embodiments of this invention, including those shown in FIGS.3-51. It is preferably a cage made of heavy duty wire screen orperforated metal that is attached (as by welding or rivets) to a rearpanel, such as panel 41 in FIG. 8. This provides a secure compartment 42for a power source accessory 43, such as an auxiliary battery, charger,or battery eliminator.

Compartment 42 is also shown in the side view of FIG. 9.

In a further alternate embodiment, shown in FIG. 10, a locking baseusing a telescoping rod 54 is shown. In this embodiment, there is nomember such as locking collar 2 or transparent panel 30 that can bereadily removed from the locking base when a computer or other personalelectronic device is not secured to the base. This should reduce theincidence of vandalism or theft of the removable item which would renderthe base unusable. In FIG. 10, one end of bar 54 is attached to the leftside panel member 51 of base 50 via a pivotable fastener, such as balljoint 53. After the notebook computer or other personal electronicdevice is inserted between sides 51 and 52, bar 54 is swung over thelower (hinge) portion of the notebook computer's screen, such as aliquid crystal display (LCD) screen and is elongated so as to insertlock plug 55 through locking hole 56 in right side 52. A lock (notshown), such as padlock 20, is then inserted through the hole in plug 55thus locking computer to base.

Alternate locking members include locking members such as vinyl cladsteel cable 60 shown in FIG. 11, and the flexible tubing clad chain 65shown in FIG. 12. These two devices do not require a ball jointattachment to left flange 51. Cable 60 can be simply inserted through ahole in flange 51 and then retaining washer 61 can be permanentlyattached as by spot welding. Lock plug 55, used as for telescoping rod,is attached to the distal end of cable 60. Chain 65 can be attached toflange 51 in a similar fashion by attaching washer 66 to its proximalend after threading through a hole. The distal end of chain 65 has anelongated link 67 with stop washer attached. The padlock is engagedthrough this link after it emerges through hole 56 in side 52.

FIG. 13 shows an alternate embodiment using a separate locking base 81used with a notebook computer or other personal electronic device lock80 which slides in from the left so that one or more base pads 87 areretained by one or more brackets 82 on base 81. FIGS. 13 and 14 alsoshow a clamp 86 which secures the lock in place by clamping the lockover a working surface, such as a table top 85.

A better view of this is the side edge view of FIG. 14. Clamp 86 slipsover the edge of work surface 85. Locking bar 84 is captive in leftbracket of computer or other personal electronic device lock 80, but itcan swing out to permit access of computer or other personal electronicdevice display. The distal end 88 is grooved to accommodate a key lockto secure the computer or other personal electronic device as well aslock 80 to base 81. The long neck portion of base 81 from clamp 86 tobrackets 82 positions the computer or other personal electronic deviceat a convenient distance from the front edge of table working surface85. The detail of clamp 86 in FIG. 13A shows how screw 92 with optionalsecurity head 91 is screwed into the bottom surface of table workingsurface 85 via pointed end 93.

FIG. 13B shows how tang 97 prevents screw 91 from being loosened whenlock 95 is locked via key 96. Lock 95 can be easily removed from hole 94in lock bracket 90. When tang 97 is turned to position 98, screw head 91is not obstructed so that it can be removed or tightened.

FIG. 15 is a top plan view showing details of notebook computer or otherpersonal electronic device lock 80 locked to base 81 with a computer orother personal electronic device display shown in dashed lines inposition 117 and keyboard shown in dashed lines in position 118. Powersupply box 100 can pivot open in the direction of arrow 101 on shaft 102with a retaining cap; it is locked via tang 112. Notebook computer orother personal electronic device lock 80 is slid into a captive positionwithin brackets 82 retaining the edges of base plates 87 in thedirection of arrow 104. The left end of swinging locking bar 84 (whichcan swing out in the direction of arrow 103) is retained via retainingcap 105 within slotted hole 115 and an oversize hole on front of theleft bracket. Key lock 110 grasps rod end 88 of swinging locking bar 84,which maintains the security of the assemblage via bracket tang 114,which is part of locking base 81. Key 111 can be used to remove the lockbody from the end of swinging locking bar 84.

While FIG. 13-15 shows a separate over the table locking base 81 usedwith a notebook computer or other personal electronic device lock 80which slides in from the left so that base pads 87 are retained bybrackets 82 on base 81 of notebook computer or other personal electronicdevice lock 80, it is contemplated that a further alternate embodimentincludes attaching notebook computer or other personal electronic devicelock 80 directly to a work surface 85, such as a study desk, byproviding fastener receptacles within base pads 87, wherein fasteners,such as screws or bolts fasten base 81 directly to an upper side of thework surface 85, without the use of over the table base 81.

FIG. 16 shows another embodiment of a notebook computer or otherpersonal electronic device lock 130 with a telescoping width adjustingfeature to accommodate computer or other personal electronic devices ofvarying widths more securely. Base pads 136 are compatible with the useof locking base 81 of the previous embodiment to retain this continuousadjustment feature. Locking bar portions 137 and 138 are adjustable insize.

For example, as in FIG. 17, incrementally spaced detents or pins andholes may be used to facilitate width adjustment.

Alternatively, as in FIG. 16, locking bar 137 may be hollow and threadedwith a coarse thread; it is captive within left bracket 134 and slottedback hole 133. Right section of locking bar 138 is screwed into portion137 and can be quickly length adjusted by twisting it clockwise orcounter-clockwise. Horizontal section 131 fits into section 132 in atelescoping fashion. After the notebook or laptop computer or otherpersonal electronic device display is placed between the spread-apartbrackets, the brackets are pushed against its sides and swinging lockingbar portions 137 and 138 are adjusted accordingly to fit into holes inright bracket 135 for locking.

FIG. 17 shows a different width adjustable computer or other personalelectronic device lock 170 with a discrete locking mechanism includingpivoted flange 178 with peg 176 at its distal end. Flange 178 is pivotedon pivot 182, such as a rivet, attached to outer telescoping member 132of notebook computer or other personal electronic device lock 170. Whenswung in the direction of arrow 179, flange 178 will force peg 176through hole 175 in telescoping section 132 and further into one of theholes 180 in inner telescoping member 171 when in positionalregistration. Flange 178 is locked in position when hole 185 is inpositional registration with hole 184 and locking bar 173 end 139 ispassed through both. The swinging locking bar includes hollow sidesection 172 and inner, preferably solid, side section 173, which istelescopic within outer hollow side section 172.

FIG. 18 shows another embodiment 150 of this invention wherein thelocking base has been integrated with the notebook computer or otherpersonal electronic device lock. Clamp 153 locks onto work surface 85 asdescribed in a previous embodiment with a separate locking base 81 (seeFIGS. 13-14). Upright brackets 151 and 152 with bar 83 between capturethe notebook computer or other personal electronic device display whichis then locked via swinging locking bar 84 and a key lock (not shown).

A related embodiment in FIG. 19 shows integrated base/computer or otherpersonal electronic device lock 160 which has one or more pivot points164 and 166 (on base part 167). Link 165 now pivots in relation to clampsection 163 such that the notebook computer or other personal electronicdevice lock 160 can be more conveniently positioned on work surface 85.

In FIG. 19, for example, clamp 163 is placed on the edge to the side ofcomputer or other personal electronic device lock base 167 instead ofdirectly in front of it as would be necessary in the embodiment of FIG.18.

The preferred low profile locking base embodiment of this invention forconsumer use is detailed in FIGS. 20-27.

FIG. 20 shows a low profile locking base 200 with narrow base 202 andlow rise back 201. It is screwed to work surface 285 via fasteners, suchas screws 203. Locking bar 284 with optional rubber or elastomergrommets 205 and machined end 288 is used to lock the display of anotebook or laptop computer or other personal electronic device (notshown) to locking base 200. End 288 is passed through hole 204 andlocked with pin lock 110. Key 111 is used to unlock and remove thecomputer or other personal electronic device.

The preferred simpler method of use of a locking base is not to screw itdown as shown in FIG. 20 but instead to create a portable locking kit byadding a clamp 211 and cable 210 as shown in FIG. 21.

Due to the low profile design with a narrow base, all components of theportable kit conveniently fit into a tubular carrying case (not shown).

FIG. 21 also shows Clamp 211 having a fastener, such as a screwsubassembly, including screw 212 and short container, such as a cylinder216, with transverse cable attachment hole 213. At the first end ofcable 210 is a ferrule 215 with a transverse hole. This fits throughhole 213. The cable is threaded through hole 213 after clamp 211 issecured using the appropriate tool to tighten screw 212. The distal endof cable 210 has ferrule 214 with enlarged end which does not fitthrough hole 213.

FIG. 22 shows the arrangement more clearly. It is noted that cylinder216 has distal hole 220 which accommodates the screw head and also has ascrew clearance hole 221 on its top surface. After cable 210 is threadedthrough hole 213, a tool cannot reach screw head 222 to loosen clamp 211since access is denied through distal hole 220. After cable 210 isinstalled through cylinder 216, the end 288 of locking bar 284 is passedthrough the transverse hole in ferrule 215 prior to locking bar 284 tobase 200.

In an alternate embodiment of the clamp screw subassembly no tool isrequired to tighten or loosen clamp 211.

For example, an exploded view of subassembly 230 is shown in FIG. 23with end cap 231 pushed down over clamp screw 233 and press fit into theend of knob 235. Optional pins 238 can be driven radially to insurepositive attachment. Cap 231 has screw clearance hole 232 at its center.Screw 233 becomes captive as a subassembly with tall head 234 withinknob 235 once cap 231 is attached. Offset transverse hole 237 in knob235 goes through both walls and is sized for cable attachment.

FIG. 24 shows the underside of cap 231 revealing hexagonal recess 240sized to engage bolt head 234.

FIG. 25 is a top view of subassembly 230. In the side crossection ofFIG. 26, bolt head 234 is seated in recess 240 of cap 231. This is priorto the insertion of cable 210 through holes 237. Clamp 211 can betightened in this depicted configuration by turning knob 235 sincerecess 240 acts as a socket wrench to bolt 233. It is noted also thatthe size of head 234 interferes with the placement of hole 237 therebypreventing insertion of cable 210 while head 234 is seated in recess240.

If knob 235 is pushed up as shown in FIG. 27, cable 210 can now beeasily inserted through holes 237 adjacent to screw 233 and spacing head234 away from recess 240. In this configuration with cable 210 installedthrough knob 235, if turned, knob 235 will spin freely regardless of theup or down forces exerted. Clamp 211 can only be removed after cable 210is removed and head 234 is re-seated in recess 240. In lieu of anon-standard screw 233 with tall head 234, a standard hex screw can beused with a nut screwed up against the head and adhesively bonded as aunit. A washer between the nut and the screw head would only enhance theoperation creating a more positive barrier with cable 210.

In an alternate protruding member locking embodiment of this invention,spikes, security rods or strips are used to secure a personal electronicdevice, such as a notebook computer, cellphone, personal digitalassistant (PDA) or electronic music/video player (i.e. iPod®).

For example, in FIG. 28, a notebook computer or other personalelectronic device with base 275 and display 276 is shown. One of thethree through-holes is required for this embodiment. Hole 278 is at thehinge line, while hole 279 is through the display housing; hole 277 isdiagonally through one of the front or rear corners of the base.

FIG. 29 shows locking rod or spike 285 which is inserted in any of thethree hole locations discussed. Ferrule 286 with a groove near itsdistal end is then inserted through the transverse hole of spike 285 andlocked with pin lock 110. Ferrule 286 is securely attached to cable 210which had been passed through knob 235 after clamp 211 had beentightened at the edge of a table or desk top. In this manner, theillustrated notebook computer or other personal electronic device issecured via a secure cable.

In a variation of this embodiment, the separate spike 285 is replaced bya captive security rod 291 as shown in FIG. 30. Note that rod 291 may beattached either to one end of the hinge or alternatively to the topsurface of the base of computer or other personal electronic device 290at any convenient location where space permits. Rods 291 are stored in arecessed position with only a small knob protruding so that they may beeasily grasped to unlock into the extended position to expose atransverse hole. Ferrule 286 and lock 110 are then used in the samemanner as with the separate spike 285.

In another spike variation shown in FIG. 31, long spike 296 is used tosecure computer or other personal electronic device 294 which has a hole295 through its base. Hole 295 is placed over pre-existing hole 298through table top 293; then spike 296 is inserted such that transversehole 297 is accessible beneath table top 293. Then transverse pin 299with a groove adjacent its distal end is inserted through hole 297 andlocked with pin lock 110. Thus this variation locks a notebook computeror other personal electronic device using a spike without the aid of acable.

In another embodiment shown in FIG. 32 with a flexible locking strip301, a detail of notebook computer 304 with display 305 and keyboardportion 306 is shown adjacent to clamp 302. Flexible locking strip 301is shown prior to insertion through the hinge gap between display 305and keyboard 306 (not shown) and further between bottom jaw 314 and topmovable jaw 312 of clamp 302.

In lieu of being inserted within a hinge gap, flexible locking strip 301may be inserted within a thin, longitudinally extending slot, similar toholes 277, 278, 279 for rod 285 of FIG. 29.

FIGS. 33, 36 and 37 show other features of clamp 302 with movable top311 and stationary base 313. Locking strip 301 is clearly shown in topview and side view in FIGS. 34 and 35 respectively. Wedge stop 325 isshown at one the proximal end with narrow rectangular strip 326 at thedistal end. Wedge stop 325 is preferably plastic which is bonded tostrip 326 as by overmolding. It is noted that base portion 313 of clamp302 is typically screwed to work surface 303 via screws 322, however,alternatively security cable 320 with secured distal end (not shown) canbe used.

Gripping means, such as serrations 337 in FIG. 36, form lower static jaw314 of FIGS. 32 and 33; they engage strip 301. Hole 336 is used foroptional cable 320. Holes 322 a accommodate fasteners 322, such asscrews. Rectangular holes 335 accept tabs 339 of upper movable jaw 311to form a hinge. The vertical wall 313 a of base 313 can bealternatively joined to movable section 311 via ordinary hinges.

As in FIGS. 38 and 39, spring 319 tends to keep jaws 312 and 314slightly apart unless lock 317 is locked via key 318. In that case ifkey 318 is rotated while moving member 311 is pressed down, lock tang331 will engage lock recess 316 at the distal end of spring 319; recess316 is attached to base 313. This action will lock locking strip 301between jaws 312 and 314. Note that lock 317 is attached to hinged part311 via a fastener, such as lock nut 330.

FIGS. 40-43 show notebook computer 304, cellular phone 346, PDA 347 andpersonal DVD player 348 each with hinge gap 345. In addition, the entrypath of locking strip 301 is shown by arrows in FIG. 40.

FIG. 40 also shows a further alternate embodiment whereby the housing ofnotebook computer 304 contains a slot 326 for insertion of a flexible orrigid locking strip 328 therethrough.

FIGS. 44-47 relate to an alternate embodiment of clamp 355 whichincorporates a leaf spring 358 to impart locking force to locking strip301 when shackle 366 of padlock 365 is passed through lock loops 362 andhandle loop 376 (as in FIG. 46). In this embodiment, shallow recess 359with transverse serrations aggressively grasps strip end 326 underbending force of spring 358, which itself can have optional transverseserrations on its contact surface.

When handle 357 is free to swing up, strip end 326 can be easily passedbetween brackets 371 which are spaced apart a distance “W” (as in FIG.45) to accommodate the width of strip end 326. Base 356 is secured towork surface 303 via fasteners, such as screws 369, which are passedthrough countersink holes 367 (as in FIG. 45). Leaf spring 358 is swagedor brazed at region 363 within slot 373 of handle 357. Hole 375 in loop376 accommodates shackle 366. It is noted that spring 358 has to be bentsomewhat for handle 357 to be in registration with the holes in padlockbrackets 362. This bending also permits clamp 355 to accommodate stripends 326 of varying thicknesses. Also, with respect to the geometry ofspring 358 in FIG. 44, if a pulling force is placed on locking strip301, frictional forces will tend to rotate the free end of spring 358 ina counter-clockwise direction thereby increasing clamping force on stripend 326; this further counteracts the pull-out force. Since spring 358is wider than handle 357 (as in FIG. 47), centering washers 377 are usedon either side of it to increase the combined width to X which is justslightly smaller than W. Rivet 360 in brackets 361 acts as an axle forhandle 357; hole 372 is a clearance fit for rivet 360.

FIG. 48 illustrates alternate embodiment locking strip 390 with lockingwedge 391, strip 393 and end hole 392. Locking strip 390 may be rigid orflexible.

Dashed lines 305 of FIG. 48 show the position of a computer display ifthis is being secured. Added hole 392 permits at least three non-clamplocking methods to be used. These are illustrated in FIGS. 49-51; forclarity, no item is shown being locked in these FIGS. 49-51.

It is understood that instead of being inserted through a hinge gap,locking strip 390 may be first passed through a thin, longitudinallyextending slot in the housing of the personal electronic device, such asa notebook computer, instead of a round hole provided for a rod 285 or296, as is shown in FIGS. 29-31. In this case, the thinness of the slot327 for strip 328 minimizes any intrusion into the interior of the wallsof the personal electronic device, such as a notebook computer 305 andthe like, with its intricate wiring located in a tight space within thewalls of the notebook computer 305, or other personal electronic device.

The strip 390 may be a rigid rectangle or other geometric shape.Additionally strip 390 may be flexible. If flexible, strip 390 may passthrough a slot in the housing of the personal electronic device, or ifthe device is hinged, through a hinge gap between the display of thedevice and the main body of the device being secured.

In FIG. 49, stud 395 is attached to and protrudes from work surface 303.Hole 392 is simply passed over the distal end of stud 395 and then theshackle of padlock 397 is passed through the transverse hole in stud 395to lock strip 390.

In FIG. 50, secure cable 400 with collar 402 and a rigid stud at itsdistal end is used to secure strip 390. After the rigid stud is passedthrough hole 392, cable lock 401 is snapped over the end of the studthereby securing strip 390.

In FIG. 51, free cable 405 with lock member 406 permanently attached ispassed through hole 392. Since member 406 is a bulge larger than thediameter of hole 392, locking strip 390 will be secured when the distalend of cable 405 is looped or otherwise secured to work surface 303 orto some point adjacent to it.

A locking device for locking an iPod® to a table top is illustrated inFIGS. 52-56. It includes several distinct parts.

For example, FIG. 52 shows metal frame 500 which is sized to encirclethe iPod® 550. The iPod® 550 is inserted from the back and its frontfaces forward with edge 505 preventing the iPod® 550 from fallingthrough large opening 507. Opening 502 on one end of housing sides 501is to accommodate the iPod® connector.

Side ears 503 with holes 504 for rod 510 (as in FIG. 53) are used tolock frame 500 to clamp 520 (as in FIG. 54) with the aid of bent tab506.

FIG. 54 shows clamp 520 which is tightened against table top 85 bylifting spherical knob 530 thereby engaging square feature under head527 of screw 526. Offset transverse hole 531 in knob 530 is sized forthe diameter of locking pin 510 with head 511 and groove 512 at thedistal end. Although a radial groove is shown in FIG. 53, other featurescompatible with a particular pin lock may be used instead. A clampinggroove 522 is formed by side extension 521; this receives the end ofbent tab 506 of iPod® frame 500.

After tightening of clamp 520 by lifting and turning knob 530 to forcepad 524 against surface of table top 85, knob 530 can be turned to anydesired orientation when it is down from head 527 and thereforedisengaged. When secured, the back side of the iPod® 550 rests at anangle against or close to rounded corner 532 of clamp 520.

FIG. 55 is a front view of frame 500 secured to clamp 520. Forillustrative purposes, the iPod® 550 is not depicted secured insideframe 500 in this view. The details of the engagement are viewed throughfront opening 507. Except for the presence of key 111 in pin lock 110,frame 500 is secure; it may be stored this way when not in use.

In FIG. 55 pin 510 is clearly shown penetrating the sides of frame 500(at holes 504), as well as transversing offset knob hole 531. Tab 506 isshown in groove 522 formed by feature 521. On each side of 521 areblocks 540 attached to the end housing of frame 500. These aid inlocating frame 500 laterally within the grasp of clamp 520. They alsoprovide a secure groove to receive the end of the iPod® 550 betweenblocks 540 and front frame 505.

In the configuration shown in FIG. 55, knob 530 cannot be lifted veryfar nor rotated, since tab 506 limits lifting and rod 510 and tab 506prevent rotation.

FIG. 56 shows the same view with iPod® 550 secured within frame 500.Although it is not shown in this view, reference to FIG. 54 reveals thatframe 500 and iPod® 550 are tilted with respect to the edge of table top85, with the back side of iPod® 550 at or near rounded corner 522.Connector 551 is shown plugged into iPod® 550 with wire leads 552.

FIGS. 57-60 illustrate the preferred embodiment of a digital music/videoplayback device security frame. FIG. 57 shows music/video playbackdevice 660, such as, for example, an iPod® digital music/video playbackdevice of Apple Corporation, being inserted into security frame 640through its open edge; note that the top and bottom edges are U-shapedchannels which terminate in a flat back edge 642. Also shown is steelcable 625, cable clamp 600, and lock 630 with its unique circular hasp;a standard key-operated or combination padlock can be substituted.

The operation of clamp 600 is described by the exploded view of FIG. 58.Frame 601 is shown in crossection with threaded hole 602 in lower jawsection and optional resilient pad 603 to prevent marring of desk ortabletop. An optional four-sided metal security box 605 is shown withscrew clearance hole 606. Box 605 is slipped over screw 617 between knob610 and clamp frame 601 to minimize access to the shank of screw 617 asby bolt cutters; it fits over the sides of frame 601 and is pushed up byknob 610 as screw 617 is advanced. (Box 605 is not used in theillustration of FIG. 57.) The minimum attachment edge thickness M is afunction of screw 617 length. The range of adjustment “R” is noted.Screw 617 is a standard carriage bolt with smooth rounded head 619 andsquare under-head shank 618. Knob 610 has blind bottom end hole 611 witha diameter slightly larger than that of bolt head 619. At the distal endof blind hole 611, is square hole 612 which permits egress of thethreaded portion of screw 617 but engages square shank 618 when pulleddown and turned slightly into registration. Clamp 600 is assembled bypushing screw 617 through knob 610 (and box 605, if used) and thenthreading into hole 602 of clamp frame 601.

Clamp 600 is placed over the edge of a table or desk as shown in FIG. 59and knob 610 is used to tighten screw 617 by keeping a slight downwardpressure on it while turning. Then knob 610 is pushed up creating aspace between head 619 and the distal end of blind hole 611 therebydisengaging square shank 618. In fact, head 619 should be belowtransverse hole 614 which is tangent to the position of threaded portionof screw 617 (see FIG. 58). At this point, cable ferrule 626 (withdiameter D1 smaller than the diameter of transverse hole 614) isintroduced with the entire cable following until cable stop 628 withdiameter D2 is encountered. D2 is larger than hole 614 diameter. It isnoted that with cable 625 inserted through knob 610, square shank 618 isprevented from engaging square hole 612 because head 619 cannot get pastcable 625 within hole 611. Thus any rotation of knob 610 while cable 625is present will not loosen (or tighten!) screw 617. To remove clamp 600,cable 625 must be completely withdrawn from transverse hole 614; slightpulling on knob 610 against screw head 619 will engage shank 618, andturning and loosening can proceed to effect removal.

FIG. 59 shows music/video playback device 660 secured to a desktop viaclamp 600 and cable 625. Connector opening 645 is located in a bottomedge of security frame 640; a similar opening is in the top edge (notshown). The hasp of lock 630 engages both top loop extension 643 andbottom loop extension 644 as well as hole 627 of cable ferrule 626 tobridge open edge 641 and attach frame 640 to secure cable 625.

FIG. 60 shows an alternative attachment method which does not use clamp600 nor cable 625. Here, frame 640 is directly attached to backpack 652by lock 630 engaging both loop extensions 643 and 644 as well as ring650 which is attached via sewn strap 651. A similar method can be usedto attach frame 640 to a belt loop or to attachment rings on luggage,briefcases, pocketbooks, etc.

FIG. 61 shows frame 670 which is a further alternative embodiment of asecurity frame for a digital music/video playback device. Frame 670includes two right angle sections 671 and 672 hinged at 673. Note thatwhen distal end loops 676 and 677 are swung into registration, arectangular frame sized to accommodate a digital music/video playbackdevice is formed. The digital music/video playback device is held inplace by bent-over tabs 675. Openings 674 and 675 accommodate digitalmusic/video playback device connectors. Frame 670 can be attached to asecure cable and locked by engaging a distal cable ferrule as well asloops 676 and 677 in the hasp of a padlock.

Attachment to other objects without cable or clamp as shown for thepreferred embodiment is possible in similar fashion for frame 670.

FIGS. 62 and 63 show alternate embodiment locking frame 690 for digitalmusic/video playback device 660. The open long edge 691 permitsinsertion and retrieval of digital music/video playback device 660. Opencentral area 692 at the top edge of frame 690 provides access toattachment socket at the bottom of digital music/video playback device660 if so equipped. Frame 690 has a low wall 694 and bottom framemembers 693 which capture device 660. Note padlock hole 696 on a sideextension of the top frame 690 edge.

FIG. 63 shows a portion of garment 700 with belt 702 and belt loop 701which engages padlock 703 via hasp 704 which also goes through hole 696.Digital music/video playback device 660 is retained within frame 690 bythe interference of hasp 704; it dangles with screen toward the bottomwhich facilitates easy reading while still attached to belt loop 701.

FIGS. 64 and 65 show alternate embodiment locking frame 710 with digitalmusic/video playback device 725.

In FIG. 64, digital music/video playback device 725 is being inserted orwithdrawn from frame 710 through band loop 714 which has a hole 715 on ashort extension for attachment. Frame 710 has a back side 711 with opencentral area, low guidance sides 712 and a distal hook 713 which engagesthe top (screen) end of digital music/video playback device 725 bylooping over the front surface.

FIG. 65 shows digital music/video playback device 725 secured withinframe 710 by padlock 703 which also engages belt loop 701. Hasp 704prevents digital music/video playback device 725 from being withdrawnthrough band loop 714.

FIGS. 66 and 67 show alternate embodiment locking device 750 which is adiagonal bar 752 with distal pocket 751 and proximal pocket 753 formedof two orthogonal sides with locking holes 754. Note how hasp 704 ofpadlock 703 will secure digital music/video playback device 760 tolocking device 750 by preventing the corner of device 760 from beinglifted out of pocket 753. Distal pocket 751 engages the oppositediagonal corner of digital music/video playback device 760.

A prior art computer security cable 800 is shown in FIG. 68. It is aKENSINGTON® cable with their special lock 802 permanently attached via aswivel coupling 803 to steel cable 801. The other end of the cable ispermanently formed into a loop 805 by ferrule 806. Lock 802 hasprotruding rectangular feature 804 that mates with the KENSINGTON®recess in a portable computer. In normal use, lock 802 is passed throughloop 805 also engaging a secure anchoring member such as a pipe orhandrail prior to locking it into the recess in the computer.

FIG. 69 shows an alternate embodiment cable clamp 810 which is similarin features and operation to clamp 600 shown in the exploded view ofFIG. 58. Note the distinguishing feature of transverse slot 814 inoperating knob 812. In FIG. 58, transverse cable hole 614 in knob 610would not be able to admit either lock 802 not loop 805 of cable 800.

However, as shown in FIG. 70, loop 805 can enter through transverse slot814 up to ferrule 806 thereby permitting lock 802 to enter the distalend of loop 805 engaging clamp 810. In operation, clamp 810 is firsttightened onto a desk or table top using knob 812 pulled down engagingsquare feature 618 on screw 617. Then knob 812 is pushed up and loop 805is inserted through slot 814 thereby making it impossible for knob 812to re-seat onto screw head 619 to attempt to loosen clamp 810 (untilloop 805 is again withdrawn). Any cable assembly with a permanent loopat one end and a permanently attached small lock at the other end can beaccommodated by cable clamp 810. A small hasp lock can be used; then thenotebook computer or other device to be secured simply needs a securelyattached loop, not a specially designed recess.

FIG. 71 shows another embodiment of cable clamp 830 which has a griprange adjusting feature. The clamp frame is in two parts, top jaw part831 and bottom jaw part 832. Jaw part 831 is pinned or otherwise rigidlyattached to body screw 833. Bottom jaw part 832 can rotate on screw 833by virtue of a threaded hole, thereby expanding or reducing the distancebetween pad 603 and end of screw 617. Note that with slot 814 in knob812, this grip-range adjustable clamp 830 can accommodate any cable thatis compatible with clamp 810.

FIGS. 72 and 73 show a sleeve frame for slidably securing a personalelectronic entertainment device 925 within, such as an Apple® iPod®personal music player. Frame plate 901 forms a base from which shortwalls 903 and 905 extend in perpendicular arrangement. Short walls 903,905 have top ends and opposite bottom ends. Frame plate 901 similarlyhas opposite top and bottom ends, and frame plate 901 is provided with acentral opening.
